Generate CSR from Plesk directly:
1.1 Log in to your control panel and go to Domains > example.com > SSL/TLS Certificates
1.2 Click Add SSL/TLS Certificate:
1.3 Specify the following certificate parameters:
-
Certificate name. This will help you identify this certificate in the repository.
- Bits. Choose the encryption level of your SSL certificate. In Plesk Onyx, 2048, 3072 and 4096 bits are available.
- Country, province, location (city), organization name (company). The values you enter should not exceed the length of 64 symbols.
- The domain name for which you want to purchase an SSL certificate. This should be a fully qualified domain name. Example: example.com.
-
Email: The website administrator's email address
Make sure that all the provided information is correct and accurate, as it will be used to generate your private key.
1.4 Click Request
Plesk will generate your private key and certificate signing request (CSR) and add them to your certificates repository (Domains > example.com > SSL/TLS Certificates).
1.5 Now that the CSR has been generated, you need to provide it to the Certificate Authority of your choice to purchase a certificate from them. In the list of certificates in Domains > example.com > SSL/TLS Certificates, click the name of the certificate you need.
1.6 Locate the CSR section on the page, and copy the text that starts with the line -----BEGIN CERTIFICATE REQUEST----- and ends with the line -----END CERTIFICATE REQUEST----- to the clipboard.
1.7 Locate the Private key below the CSR on the page, and copy the text that starts with the line -----BEGIN Private Key----- and ends with the line -----END Private Key----- to the clipboard.
1.8 Provide the CSR to the Certification Authority when purchasing the certificate. Once you complete the purchase, you will be given the certificate in the form of either a *.crt file, a *.pem file, or in text form.
